Level(Add1quart)
AMGvehicles: theengineoil level is toolow.
XCheckthe oil level when next refueling, at the latest
(Ypage 307).
XIf necessary, add engine oil (Ypage 308).
XHave the engine checked ataqualified specialist workshop if
engine oil needs to be added more often than usual.
!Avoid long journeys with too little engine oil. The engine will
otherwise be damaged.
Information on approved engine oils can be obtained from any
qualified specialist workshop or on the Internet at http://
bevo.mercedes-benz.com.

Fuel Level Low
The fuel level has dropped into the reserve range.
XRefuel at the nearest gas station.
There is onlyavery small amount of fuel in the fuel tank.
XRefuel at the nearest gas station without fail.

Gas Cap Loose
The fuel system pressure is too low. The fuel filler cap is not closed
correctly or the fuel system is leaking.
XCheck that the fuel filler cap is correctly closed.
If the fuel filler cap is not correctly closed:

the card into the card slot on the COMAND
system before saving.
Aroute can be prepared and sent either by a
customer service representative or via the
mbrace portal on the Internet.
Each route can include up to 20 way points.

Adding engineoil
GWARNING
If engineoil comes intocontactwithhot
componentsintheenginecompartment, it
may ignite. There isariskoffireand injury.
Makesurethatengineoil is notspilled next
to the filler neck. Let the enginecool down
and thoroughly clean the engineoil off the
componentsbefore starting the engine.
HEnvironmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful
to the environment.
!Only use engineoils and oil filtersthat
have been approved for vehicles with a
servicesystem. You can obtainalist of the
engineoils and oil filterstested and
approved in accordance with the
Mercedes-Benz Specificationsfor Service
Productsatany Mercedes-Benz Service
center.
Damage to the engineorexhaust system is
caused by the following:
Rusing engineoils and oil filtersthat have
not been specifically approved for the
servicesystem
Rreplacing engineoil and oil filtersafter
the interval for replacementspecified by
the servicesystem has been exceeded
Rusing engineoil additives.
!Do not add too much oil. adding too much
engineoil can result in damage to the
engineortothe catalytic converter. Have
excess engineoil siphoned off.
Example: engineoil capXTurn capcounter-clockwise and remove
it.
XAdd engineoil.
If the oil level is at or below the MIN mark
on the oil dipstick, add 1.1 US qt(1.0 liter)
of engine oil.
XReplace capon the fillerneck and turn
clockwise.
Ensurethatthe cap locks into place
securely.
XCheck the oillevel againwith the oil
dipstick (Ypage 307).

Checking coolant level
GWARNING
The engine cooling system is pressurized,
particularly when the engine is warm. When
opening the cap, you could be scaldedbyhot
coolantspraying out. There isarisk of injury.
Let the enginecool down before openingthe
cap. Wear eye and hand protection when
openingthe cap. Open the cap slowly half a
turn to allow pressure to escape.

Maintenance and care

Curbweight
The weight ofavehicle with standard
equipment includingthemaximum capacity
of fuel, oil and coolant.Italso includes the air-
conditioningsystem and optional equipment
if these are installed in the vehicle, but does
not include passengers or luggage.
Maximumload rating
The maximum tireload is the maximum
permissible weight in kilograms or lbs for
whichatireisapproved.
Maximumpermissible tirepressure
Maximum permissible tirepressure for one
tire.
Maximumload on one tire
Maximum load on one tire. This is calculated
by dividingthe maximum axle load of one axle
by two.
PSI (pounds per squareinch)
Astandardunitofmeasure for tire pressure.
Aspect ratio
Relationship between tire height and tire
width in percent.
Tirepressure
This is pressure inside the tire applying an
outward forcetoeach square inch of the tire's
surface. The tire pressure is specified in
pounds per square inch (psi), in kilopascal
(kPa) or in bar. The tire pressure should only
be corrected when the tires are cold.
Cold tirepressure
The tires are cold:
Rif the vehicle has been parked without
direct sunlight on the tires for at least three
hours and
Rif the vehicle has been driven for less than
1mile (1.6 km).
Tread
The part of the tire that comes intocontact
with the road.
Bead
The tire bead ensures that the tire sits
securely on the wheel. There are several steel
wires in the bead to preventthe tire from
comingloose from the wheel rim.
Sidewall
The part of the tire between the tread and the
bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kilograms (5 lbs).
These optional extras, such as high-
performance brakes, level control,aroof rack
orahigh-performancebattery, are not
included in the curb weight and the weight of
the accessories.
TIN (Tire Identification Number)
This isaunique identifier which can be used
byatire manufacturer to identify tires, for
example foraproduct recall, and thus identify
the purchasers. The TIN is made up of the
manufacturer's identity code, tire size, tire
type code and the manufacturing date.
Load bearing index
The load bearing index (also load index) is a
code that contains the maximum load bearing
capacity ofatire.
Traction
Traction is the result of friction between the
tires and the road surface.
Treadwear indicators
Narrow bars (tread wear bars) that are
distributed over the tire tread. If the tire tread
is level with the bars, the wear limit ofin
(1.6 mm) has been reached.

Wheels and tires

Occupant distribution
The distribution of occupantsinavehicleat
their designated seating positions.
Total load limit
Rated cargo and luggageloadplus
68 kilograms (150 lb) multiplied by the
number of seats in the vehicle.

Flat tire
You can find information on whattodointhe
event ofaflat tire in the "Breakdown
assistance" section (Ypage 321).
Information on driving with MOExtended tires
in the event ofaflat tire can be found under
"MOExtended tires (tires with run-flat
characteristics" (Ypage 321).
Vehicle with emergency sparewheel:in
the event ofaflat tire, the emergencyspare
wheel is mounted as described under
"Mountingawheel" (Ypage 358).
Rotating the wheels
GWARNING
Interchangingthe front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions.
The wheel brakes or suspension components
may also be damaged. There isarisk of
accident.
Rotate front and rear wheels only if the wheels
and tires are of the same dimensions.
!On vehicles equipped withatire pressure
monitor, electronic components are
located in the wheel.
Tire-mounting tools should not be used
near the valve. This could damage the
electronic components.
Only have tires changed ataqualified
specialist workshop.
Always observe the instructions and safety
notes in the "Mountingawheel" section
(Ypage 358).
The wear patternsonthe front and rear tires
differ, depending on the operating conditions.
Rotate the wheels beforeaclear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires
in the center.
If your vehicle's tire configuration allows, you
can rotate the wheels according to the
intervals in the tire manufacturer's warranty
book in your vehicle documents. If this is not
available, the tires should then be replaced
every 3,000 to 6,000 miles (5,000 to
10,000 km), or earlier if the tire wear requires
this. Do not change the direction of wheel
rotation.
Cleanthe contact surfaces of the wheel and
the brake disc thoroughly every timeawheel
is interchanged. Check the tire pressure and,
if necessary, restart the tire pressure loss
warning system or the tire pressure monitor.
Direction of rotation
Tires withaspecified direction of rotation
have additional benefits, e.g. if there isarisk
of hydroplaning. You will only gain these
benefits if the correct direction of rotation is
maintained.
An arrow on the sidewall of the tire indicates
its correct direction of rotation.
Storing wheels
Storewheels that are not being used inacool,
dry and preferably dark place. Protect the
tires from oil, grease, gasoline and diesel.
Cleaningthe wheels
GWARNING
The water jet fromacircular jet nozzle (dirt
blasters) can cause invisible exterior damage
